Hi Murdoch,

Thanks for your quick answer.

First : I have a 32 bits R running on a 64 bits Windows. So I think I can load 
32bits DLL ?

Yes.

I haven't understood what I must give to is.loaded as parameter : the name of 
the DLL, the full path to it, the name of a routine in it, the value given by 
dyn.load (in fact this gives an error) ?

The name of a routine, e.g.

is.loaded("supsmu")

(which gives FALSE in current R).



About help : the only example, for is.loaded, I found in fullrefman.pdf was 
about dyn.load but is ununderstandable (?) because we have not the dyn.load 
command in the example. And if I write ?is.loaded in R I get nothing !!

Sounds as though you are using a very old or broken version of R. What does sessionInfo() give? You should be using R 3.2.3. If you're using an older one, you're on your own.
